error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

timeout

timeout specifies the amount of time in seconds to wait for samples to become available. If the time elapses, the node returns an error and any samples read before the timeout elapsed. The default timeout is 10 seconds. If you set timeout to -1, the node waits indefinitely.

If you set timeout to 0, the node tries once to read the requested samples and returns an error if it is unable to.
